1 CampusMapper a light-weight internet mapping tool using MySQL, Tomcat and SVG Barend Köbben, K Stephanie Krane International Institute for Geo-information Sciences and Earth Observation (ITC) PO Box 6, 7500AA Enschede (The Netherlands) {kobben,krane}@itc.nl INTERNATIONAL INSTITUTE FOR GEO-INFORMATION SCIENCE AND EARTH OBSERVATION

2 Outline Where CampusMapper came from GDI LIGHT RIMapper Wireless Campus LBS What CampusMapper is Demo (or geoserver.itc.nl/campusmapper) Where CampusMapper is going to RIMapperWMS? ITC Department of GeoInformation Processing Barend Köbben & Stephanie Krane 2

3 GDI LIGHT Lightweight Geo-Data Infrastructure based on open standards/open source software testbed/playing ground at ITC for research: PhD & MSc work, projects server-side focus on MySQL/PostGIS, Java, open source OWS services client-side focus on SVG first project was RIMapper ITC Department of GeoInformation Processing Barend Köbben & Stephanie Krane 3

4 RIMapper - DB MySQL/PostGIS DB with OGC SFS support stores all features as objects with OGC geometry ITC Department of GeoInformation Processing Barend Köbben & Stephanie Krane 4

5 RIMapper - config simple XML map configuration files to define map layout and interactivity ITC Department of GeoInformation Processing Barend Köbben & Stephanie Krane 5

6 RIMapper - app Java servlets to deliver SVG output (=application) makesvg XML2SVG parsexml ITC Department of GeoInformation Processing Barend Köbben & Stephanie Krane 6

10 Wireless campus University of Twente Europe s largest uniform hotspot 140 ha campus (covered in- and outdoors) + Enschede city centre (outdoors) 650+ individual access points every-day working LAN based on WiFi testbed for wireless and mobile applications ITC Department of GeoInformation Processing Barend Köbben & Stephanie Krane 10

11 Wireless Campus Location Based Services informal co-operation between ITC & UTwente driven by research projects + UT IT-dept + SVGopen2005 conference set up infrastructure necessary for LBS combines input from several research projects with practical application of techniques Wireless Campus LBS is intended to serve as a testbed for research as well as to benefit from research outcomes to provide useful working services for the UT campus population ITC Department of GeoInformation Processing Barend Köbben & Stephanie Krane 11

12 FLAVOUR prototype: architecture Friendly Location-aware conference Assistant with privacy Observant architecture Location Managers Jini based (Java networkcentric services) provides client with location registers with: Jini Lookup Services: pull (find others, locate resources) push (communicate with others, conference messages) Client application Mapping System Jini Lookup service register/lookup location manager location client manage location 1 client manage client n fixed infrastructure WiFi network MySQL geodb (APs, geodata) Mapping system RSS user acquisition interface client ITC Department of GeoInformation Processing Barend Köbben & Stephanie Krane 12

13 FLAVOUR prototype: interface ITC Department of GeoInformation Processing Barend Köbben & Stephanie Krane 13

14 From Flavour to CampusMapper Mapping system based on RIMapper Added features extraction in DB - based on bounding boxes The system seemed useful for more than Wifi localization: basis for quickly and easily customised maps of the campus CampusMapper pilot DHTML interface generates GET/POST requests JavaBeans store user/session settings ITC Department of GeoInformation Processing Barend Köbben & Stephanie Krane 14

18 Future: towards RIMapperWMS? Many WMS available, some with (limited) SVG output All use SVG as graphics format only SVG also can provide application logic simple WMS conformant interface to the data data includes built-in client-side GUI GUI handles the map interaction and generates further requests ITC Department of GeoInformation Processing Barend Köbben & Stephanie Krane 18
